I see. That makes lots of sense.
I have tried a number of your themes but not Parabola, I guess this is why I misunderstood it — I thought you built the preset color picker purely for the demo.
Since the preset color schemes are part of Parabola’s configurations and not other themes, you are right that having a preset picker in other demos does not make much sense and are probably not cost-effective enough.
Thank you a lot for writing such a long and detailed response!
